Description

[0001] The invention relates to an electronic power device, and more particularly to a device comprising power chips fixed on support plates, the plates being cooled by a cooling fluid. The electronic power device of invention is particularly applicable to electronic devices used in converter type circuits for distributing power in railway applications, in which the delivered current and voltage values are particularly large.

[0002] In conventional manner, it is known to cool an electronic power component by coupling it to a heat exchanger and by inserting a ceramic plate between these two components to isolate the heat exchanger electrically from the component. Thus, document FR 2 775 416 discloses an electronic power device having power chips fixed on one face of a support plate, the other face of the plate having a heat exchanger. It is also known from that document to associate support plates in pairs by placing them on opposite sides of a cooling circuit, the heat exchangers the...
